About frequency units
Frequency counts events per second. One hertz is one cycle per second, and the kilo, mega and giga prefixes work exactly as they do elsewhere in SI. Revolutions per minute is the same kind of quantity measured per minute, so 60 rpm is exactly 1 Hz.
Hertz counts complete cycles per second. This converter treats one revolution as one cycle, so 60 rpm = 1 Hz; angular frequency in radians per second would additionally involve 2π.
